measures. Pests can include ants, scale insects, mealy bugs, beetles, slugs, borers, caterpillars, nematodes,
fruit flies, mice, rats and birds. Some, or all of these, may be present on H. undatus. A soft watery rot can
occur from injury, such as sunburn, or wet conditions. For information on insect control, please refer to the
